Abstract:
Vibro-sinking cast-in-place pile is widelY used because it has many advantages.However, the problems about the construction quality are possible to happen because of thecomplicated constructive technique. This paper analyses these problems and proposed correspondingprevent methods and measures.

Abstract:
This paper analyses and studies the engineering geological characters of Redclay distributed in Taishan area. And determined that the Red clay in this area is belong to the sa-me class as distributed in south area. There is Red clay occasionally in the north latitudeof 35°~36.5° of Shandong province.

Abstract:
The substructure interface method is presented to solve contact problems ofbodies of underground structures. It can be used to effectived simulate the cracking and slidingon the interface. It can solve distribution stress and defromation characteristic on interface. Thismethod don't demand the stiffness parameters of the interface.

Abstract:
There is certain temperature difference between the surface water and groundwater in the same area in normal temperature.Percolation and supply between thes two kinds of water can make thes difference change.This paper proposed the surveying temperature in mountain area to deduce the drain volume from groundwater to river,and to search groundwater resoures and assess in quantity the groundwater.

Abstract:
In this paper, the methods of the determination and the analysis urban evolution ate discussed with the multi-period aerial image and the relevant auxiliary data. The analysis research are qualitative, positioning and quantitative for the distribution of industry, agriculture, traffic, environment and municipal work in the difference history period of urban Thegeneral character problems are concluded scientifically in the urthan evolution, and the achievementcan be used to guide urban planning and construction.

Abstract:
Test studies of refraction survey method and instantaneous mechanicalimpedance method are proceed to large model pile set on surface. The test results indicatestEat the time period wave type of refraction survey method is obvious and the effect is better.And the frequency range transmit function curve character is no reflect, and the effect is notgood. The select of the test method can not be ignored. The better dynamic test results can beobtained by comprehensively applied the time period method and the frequency range method.
